The creation of the original screen is of considerable importance in the design of light and music. Svetoteni fall primarily into two types with distinct colors and gammopathies — there takes place a combination of colors. I have developed svetograd “the Sun” combines both types of screens. In the Central part occurs range of colors, and the side beams as would decode the primary colors (Fig. 1).
Fig. 1. The appearance of svetkana “the Sun”.
Design is presented in figure 2. Around the perimeter of the round building, made of iron sheet of 1 mm thickness in the form of divergent rays set of 18 glass tubes from a blown fluorescent lamps LD or 80 LD-40. Tube shortened by using nichrome wire Ø 0.8 mm and length 15 cm, For this purpose it is connected to the step-down transformer for the 6.3 V (Fig. 3).
In the selected slice place glass tubing make a coil of wire and includes the current. When the spiral is heated, it shut off and the heated area is moistened with water. The tube in this place formed a concentric crack.
Fig. 2. Design svetkana:
1 — tube of a fluorescent lamp, 2 — upper bushing, 3 — nut M5, 4 — pin, 5 — lamp KM-12, 6 — vinyl chloride tube, 7 — bulb 220V, 8 — light, 9 — housing, 10 — lower bushing.
Fig. 3. Device for cutting tubes.
The ends of tubes closed with plugs of foam Ø 38 mm. In the extreme sleeves, a slightly off center, make a hole Ø 5 mm under studs through which the tubing is attached to the housing. Studs of steel rod Ø 5 mm. on both ends of the cut thread M5 length 10 and 15 mm.
Bushings, located near the body, make two holes Ø 5 mm: one for studs and another for the wires.
On the circumference of the housing 36 is drilled Ø 5 mm: 18 for mounting pins and at a distance of 10 mm from them 18 holes for electrical wiring.
In the middle of the body fixed 6 lamps 220 V, two painted in three colors: blue, green and red. On top of the closed bulb frosted reflector Ø 250 mm.
On each stud with the vinyl chloride pipe set for 4 lamp KM-12. They painted napolcom: mounted in a long tube — red, middle — green, short blue.
Of the six beams of each color is a garland on 220 V. It connects to the two lamps of the corresponding color, located in the body.
